2.6.1 Concatenation
It is possible to concatenate up to 4 different codes, set their length and enable a
separate transmission between them. When enabling the separate transmission one
or more global headers and terminators are added to the decoded data. The
concatenation procedure may occur in different ways depending on the number of
codes to be decoded per image:
One Code Per Scan
•
If the code resulting from the single decoding of an image belongs to one of the
code families to be concatenated, it is saved to the Lynx™ BT memory waiting
for other codes to complete the concatenation.
•
If the code belongs to the same family of a code previously saved, it overwrites
the old one.
•
If the code resulting from the decoding does not belong to one of the code
families to be concatenated, it causes the concatenation failure and clears the
temporary memory. If the "Concatenation Failure Transmission" command is set
to "Tx codes causing failure", this code will be sent in the output message.
All Codes Per Scan
•
All codes resulting from the decoding of an image and belonging to one of the
families to be concatenated are saved to the Lynx™ BT memory waiting for
other codes to complete the concatenation.
•
If one or more codes resulting from the decoding belong to the same family of
codes previously saved, they overwrite the old ones.
When the image contains no code to be concatenated, the concatenation fails and
the reader temporary memory is cleared. If the "Concatenation Failure Transmission"
command is set to "Tx codes causing failure", the codes causing the concatenation
failure will be sent in the output message.
